Optimizing and Maintaining Print Quality
Intermec designed and configured your printer to provide the best possible
print quality for both direct thermal and thermal transfer media. However,
there are many factors that you need to take into account before you can
achieve maximum print quality.
Correcting Uneven Print Quality
You may experience problems in print quality (ribbon wrinkling or light
print on one side of your label) if the printhead is not making even contact
with the label stock. This condition can happen with any size label stock,
but is most common when using narrow label stock. You need a straight-
slot screwdriver to turn the bias adjust screw.
To achieve the best print quality, adjust the bias adjust screw each time
you use media of a different width.
Note: You must properly adjust the bias adjust screw to prevent premature
printhead failure and excessive platen wear.
To adjust the bias adjust screw
1 Remove the media cover and locate the bias adjust screw.

shown. Adjusting the bias adjust screw causes the printhead to rest
evenly on the drive roller and results in even print quality.
